Belt tightening device with display for displaying tension

Abstract

A belt tightening device with a display comprises a body having a seat; one end of the seat being installed with one fixing hook; a pull rod pivotally installed to the seat; a wheel rotatably installed to the pull rod; a belt winding around the wheel; wherein when the pull rod is pulled so that wheel rotates with the pull rod; the belt will wind to tighten an object fixed by the fixing hook; a strain gauge installed at a connection between the fixing hook and the seat; an integrating unit installed at the seat and connected to the strain gauge; the integrating unit connected to the strain gauge will determine the tension of the fixing hook through the resistance; and a display installed in the integrating unit for displaying the tension determined by the integrating unit.

1. A belt tightening device with a display comprising:
 a body having a seat; one end of the seat being installed with one fixing hook; 
 a pull rod pivotally installed to the seat; 
 a wheel rotatably installed to the pull rod; a belt winding around the wheel; wherein when the pull rod is pulled so that wheel rotates with the pull rod; the belt will be wound to tighten an object fixed by the fixing hook; 
 a strain gauge installed at a connection between the fixing hook and the seat; 
 an integrating unit installed at the seat and connected to the strain gauge; wherein when the fixing hook is tightened, the strain gauge will deform due to the tension of the belt so that the resistance also changes; the integrating unit connected to the strain gauge will determine the tension of the fixing hook through the resistance; and 
 a display installed in the integrating unit for displaying the tension determined by the integrating unit; and 
 wherein the integrating unit includes a display and a push button; and 
 wherein the integrating unit further includes at least one battery as a power supply. 
 
   
   
     2. The belt tightening device with a display as claimed in  claim 1 , wherein the seat is installed with a buzzer for alerting the user as the tension is over a threshold. 
   
   
     3. The belt tightening device with a display as claimed in  claim 1 , wherein the seat is installed with a lamp for illumination in operation. 
   
   
     4. The belt tightening device with a display as claimed in  claim 1 , wherein the seat is installed with a solar energy plate as a power supply. 
   
   
     5. A belt tightening device with a display comprising:
 a body having a seat; two ends of the seat being installed with one fixing hook and a moveable hook; the fixing hook and movably hook being used to hook an object to be tied; 
 a pull rod pivotally installed to the seat; 
 a wheel rotatably installed to the pull rod and two lateral sides of the wheel being installed with two stop claws; a belt winding around the wheel; wherein in operation, when the pull rod is pulled so that the wheel rotates with the pull rod to wind the belt, the belt is tightened; and 
 a strain gauge is installed at a connection between the fixing hook and the seat; the seat having an integrating unit connected to the strain gauge; the integrating unit being installed with at least one battery as a power supply; 
 a display installed in the integrating unit for displaying the tension determined by the integrating unit. 
 
   
   
     6. The belt tightening device with a display as claimed in  claim 5 , wherein the seat is installed with a buzzer for alerting the user as the tension is over a threshold. 
   
   
     7. The belt tightening device with a display as claimed in  claim 5 , wherein the seat is installed with a lamp for illumination in operation. 
   
   
     8. The belt tightening device with a display as claimed in  claim 5 , wherein the seat is installed with a solar energy plate as power supply. 
   
   
     9. The belt tightening device with a display as claimed in  claim 5 , wherein the strain gauge is made of piezoelectric material.
